    Publication Year: 1953, Page(s):284 - 286
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (867 KB)

    After pointing out the lack of attention paid to basic methodology in the United States until very recently, the inductive and deductive methods are discussed together with the correlational and theoretical approaches to scientific research. It also is indicated that the method of theoretical science can and should be applied to the social sciences. View full abstract»

  • Amplidyne voltage regulator for turbine generators

    Publication Year: 1953, Page(s): 289
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (668 KB)

    THE USE AND DEVELOPMENT of voltage regulators over the past 50 years has produced the modern amplidyne voltage regulator. This regulator includes a voltage-sensitive circuit composed of static elements, such as transformers, reactors, resistors, capacitors, and metallic rectifiers. These are all reliable, conservatively designed components with long life expectancy. The voltage-sensitive circuit c... View full abstract»

  • A new property of 2-dimensional fields

    Publication Year: 1953, Page(s): 290
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (229 KB)

    THE GRAPHICAL MAPPING of a 2-dimensional field in a nearly closed area that is without sources is, at best, a difficult task. A typical case is that of flux down a slot. The only feasible approach is to map it by partial subdivision. This has been started in Figure 1 and continued in Figure 2. In this field, which will be called the original field, A′P is an equipotential boundary; AAȃ... View full abstract»

    MAGNETIC AMPLIFIER FEEDBACK circuits generally have no influence upon the effective input impedance of the control circuit, because the d-c feedback component flows through special feedback windings, “external feedback,” or in the load windings, “internal feedback” or “self-saturation.” Therefore, the effective impedance of the control circuit is determine...

    Possibilities for stimulating professional work still exist and are increasing for the young man who chooses work in the power field. Manufacturers and employers whose interests lie in this field should stress management positions and new developments in power generation, sources of power, high-voltage transmission, and distribution as great opportunities for young engineers.

  • Cathode-drift compensation in D-C amplifiers

    Publication Year: 1953, Page(s): 299

    THE PHENOMENON of cathode drift represents one of the more troublesome sources of drift in direct-coupled amplifiers, and although the exact mechanisms involved have not been completely explained, it is generally accepted that the conditions of drift can be simulated, for analytical purposes, by the assumption of a random noise-voltage generator in series with the cathode of the tube in question.

  • Dynamic braking on diesel-electric locomotives

    Publication Year: 1953, Page(s):300 - 305

    The increasing prominence of the diesel-electric locomotive on American railroads has given new impetus to the use of dynamic braking. A recent refinement of braking control takes advantage of additional traction-motor capacity available at low speeds and service tests have shown the operational and economic value of this form of braking.

    With industry becoming increasingly interested in the engineering graduate with strong training in basic sciences, it is time to review the causes and reasons for specialized engineering education. Options in their present form are creating some serious problems and changes in curricula should be made both to interest students in engineering and to answer industry's insistence upon more fundamenta...

  • A new heavy-duty 3-phase oil circuit recloser

    Publication Year: 1953, Page(s): 307
    Cited by:  Papers (1)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (833 KB)

    THE ECONOMIC DESIGN of automatic circuit reclosers has been made possible through the use of a series solenoid which opens the recloser when current exceeds a minimum trip value and stores energy for automatic reclosing. As the power output of the series solenoid at minimum trip current is small, this design has limited 3-phase reclosers to single-pole operation. Single-pole operation has the disa...

  • An improved magnetic servo amplifier

    Publication Year: 1953, Page(s): 308
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (280 KB)

    ONE OF THE major difficulties in obtaining high performance from a magnetic amplifier servo system has been the slow speed of response of the magnetic amplifier. Although the magnetic amplifier is a carrier-type system and as such has a minimum response time per stage of one cycle of the supply or carrier frequency, this response is usually not obtained in conventional full-wave circuitry. A major... View full abstract»

    With the range requirements for long-distance flights increasing it is imperative that the operating efficiency of the aircraft be maintained at the highest level. To attain this peak performance an automatic cruise-control computer has been proposed which is here compared with current manual techniques. View full abstract»

    IN INTRODUCING the subject of electrical maintenance in modern aircraft, it is felt that a brief history of the development of these systems is in order to show the development from the rather simple systems as used on the DC-2's and DC-3's, which were the latest design 10 to 12 years ago, to the complex maintenance required on the intricate electric systems used in the modern airplanes such as Co...

    EXPERIENCE WITH SLEET CONDITIONS on the Niagara Mohawk System has indicated that adequate planning is necessary if satisfactory results are to be secured from any sleet-melting program. This planning extends from system design, to operating procedures, to training. All must be co-ordinated to weather a severe storm successfully. Included in this planning is close contact with the United States Wea... View full abstract»

    THE PROPER application of line traps in power-line carrier systems requires the consideration of the needs of the system and the properties of the line traps. In the past, insufficient information was generally given or, in many cases, known, to realize the possible resonant conditions that could exist in an installation. Recent investigations have brought to light many of these pitfalls. View full abstract»
